Abstract
A method and system is disclosed for displaying image data of a subject and a model. The model may include an implant or item model. The model may be used to assist in validation of a procedure.
Claims20
A system to plan a procedure, comprising:
- a processor module to execute instructions to:
- access first image data of a subject having a calibration portion included in the first image data;
- calibrate the first image data using the calibration portion included in the first image data;
- segment the first image data into a first plurality of segments corresponding to a plurality of vertebrae of the subject;
- determine, using the calibrated first image data, an implant geometry based on a planned positioning of the first plurality of segments;
- access, after a portion of the procedure, second image data of the subject having an implant, the second image data having the calibration portion;
- calibrate the second image data to a same calibration as the first image data using the calibration portion of the second image data;
- segment the second image data into a second plurality of segments corresponding to the plurality of vertebrae of the subject;
- identify a geometry between the second plurality of segments;
- and
- generate a graphical representation of the determined implant geometry to be superimposed on an image of the accessed second image data and the implant;
- and
- a display device configured to display a comparison table of the planned positioning of the first plurality of segments and the geometry between the second plurality of segments.

A system to plan a procedure, comprising:
- a processor module to execute instructions to:
- access first image data of a subject having a calibration portion included in the first image data;
- reconstruct a first three-dimensional (3D) image of the subject with the accessed first image data;
- calibrate the first 3D image using the calibration portion included in the first image data;
- segment the first 3D image to generate a first plurality of segments corresponding to a plurality of vertebrae of the subject;
- determine a planned geometry of the first plurality of segments of the segmented first 3D image;
- determine, using the calibrated first 3D image, a 3D implant geometry based on the planned geometry of the first plurality of segments;
- access, after a portion of the procedure, second image data of the subject with an implant, the second image data having the calibration portion;
- calibrate the second image data to a same calibration as the first image data using the calibration portion in the second image data;
- reconstruct a second 3D image of the subject with the accessed second image data;
- segment the second 3D image into a second plurality of segments corresponding to the plurality of vertebrae of the subject;
- identify a geometry between the second plurality of segments;
- and
- generate a graphical representation of the determined 3D implant geometry to be superimposed on the reconstructed second 3D image;
- and
- a display device configured to display a comparison table of the planned geometry of the first plurality of segments and the geometry between the second plurality of segments.

A system to plan a procedure, comprising:
- a processor module to execute instructions to:
- access first image data of a subject having an initial geometry of a region of interest prior to a procedure and having a calibration portion included in the first image data;
- calibrate the first image data using the calibration portion included in the first image data;
- segment the first image data into a first plurality of regions of interest of the subject;
- generate planned image data of the subject having a planned geometry of the first plurality of regions of interest subsequent to a procedure that is different than the initial geometry;
- access second image data of the subject subsequent to the procedure, the second image data having the calibration portion;
- calibrate the second image data to a same calibration as the first image data using the calibration portion in the second image data;
- segment the second image data into a second plurality of regions of interest;
- determine a subsequent geometry of the second plurality of regions of interest;
- and
- generate a graphical representation of the determined subsequent geometry;
- and
- a display device configured to display a comparison table of the planned geometry and the subsequent geometry.
